Abstract: Heinz-Dieter Zeh's discovery that the motion of macroscopic objects can not, under typical conditions, follow the Schr\"odinger equation necessitates a suitably modified dynamics. This unfolded a long-lasting puzzle in the open quantum system context: what is the quantum counterpart of the classical Brownian motion in a gas. Presented is a criticism and an open-end discussion of the quantum linear Boltzmann and quantum Fokker-Planck equations -- with constant respect for foundational research.

Quantum decoherence from complex saddle points [0.0]
Quantum decoherence is the effect that bridges quantum physics to classical physics. We present some first-principle calculations in the Caldeira-Leggett model. We also discuss how to extend our work to general models by Monte Carlo calculations.

Quantum data learning for quantum simulations in high-energy physics [55.41644538483948]
We explore the applicability of quantum-data learning to practical problems in high-energy physics. We make use of ansatz based on quantum convolutional neural networks and numerically show that it is capable of recognizing quantum phases of ground states. The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.

Random matrices: Application to quantum paradoxes [0.0]
Recently, a geometric embedding of the classical space and classical phase space of an n-particle system was constructed and shown to be physically meaningful. Namely, the Newtonian dynamics of the particles was recovered from the Schroedinger dynamics by constraining the state of the system to the classical phase space submanifold of the space of states. A series of theorems related to the embedding and the Schroedinger evolution with a random Hamiltonian was proven and shown to be applicable to the process of measurement in classical and quantum mechanics.
